Lowering people's body temperature does have the effect of prolonging life. The average life expectancy of people living in the cold zone is 10~30 years longer than that of people living in the tropics, and the centenarians per 65,438+10,000 people are 10 to dozens of times that of the tropics. Body temperature is closely related to basal metabolic rate. When the body temperature drops, the metabolic rate also drops. When the body temperature drops to 30℃, people's metabolic rate can be reduced by half, and the body's oxygen consumption is only 50% of normal. Prolonging the cell division cycle is equivalent to delaying human aging, thus prolonging life span.
